lle it known that we. Joux (i. (i. lluLrxnu and @Lyme Oni-1N, a suhjeetot' the King of Sweden and a Citizen: ot tlie,.l"ii'itedA States,respectively. both residing at Columbus. in `they eounty of Franklin andState ot' Ohio.` have invented 'ertainy new and uset'ulv lm provementsiirTait-tups tor Milking Ap-V paratus. otivliieh the 'following is aspeellieation. v

()ur,invention relates'to` uiillv'ing apparatus and more pai'ti.'ularlyy to teat eups therefor ot' the intermittently Vinflated orpulsating'type. f

The object ot the invention is to simplify the structure as well as themeans and inode ot' voperation ot' auch devices wherebiY they will not.only be eheapeneil in Construction, but willbe more ellieient in use.positive in operatioi-i. uniform in action, and u nliliely to get outotyrepair. I

` A vturthei object of the invention is to provide a .tent `eup whiehwill be universal in its applieation to 'tents ot' varying length anddiameter whereby the saine eup may he uned without change forditl'erent. cows regardless of the relative size ot theteats. furtherobjeet of the invention is to provide a flexible lining or filler whichwill be uniform in its operation. contracting substantiallyuniformlythroughout its periphleiv at all points throughout ,its length andadapted to contract initially and to a greater degree atitslmver end,the reontrzuftiou gradv ually extending upward witlrdiminishing tension.y

A further objeetot' the invention is to provide a flexible lining orfiller inwhich the tendency to wrinkle transversely will be obviatedVand the, distortion under varying internal, and external Ipressureisreduced to minimum.` Y

A Jfurther object of the invention is to lprovide improved means forConnecting the filler or lining 'within the housine.

lVith the ,above primary and other inoi dental objects in View, as willmore fully appear in the specification, the invention consists of thefeatures ot' construction, the parts and combinations thereof,` and 'shemode of operation, or their etpiivalents, .as hereinafter described andset forth in the claims.

Referring' to the drawings. the tent Cup forming the subject4 matterhereof comprises a cylind `ieal housing;` l having about its uper edgekan outvvardl)T projecting externally threaded collar or flange 2 and atits lower end an internally threaded head l pro vided with an internalperipheral flange 5.

Leading to the interior ot' the housing 1 through the head 4 at one sideof the Central screw threaded opening thereof Ais an air conduit 6. Thisair Conduit G is connected through av pulsator or other control meanswith a suitable suction device or vacuum pump. The pulsator or controlmeans alten nateiy opens the conduit il to atmosphere and closes itwhereby the action of the Vacuuni pump is exerted therethrough to edectthepulsating action of vthe Flexible lining or filler. The constructionand operation oi the pulsator and control mechanism is fully shown anddescribed in coiiending opplication Serial No. ?.,57 to which referenceis made for a detailed description'. It is to'he undersiood, however,that the teat cupiorming the subject matter hereof is not limited to useAwith the particular pulsaior therein described but may he employed inconjunc# tion 'with other pulsators or control means for alternatelyadmitting and exhaust-ing air lnsough the conduitJ 6. The outer faces ofthe flanges 2 and 5 are preferably, thoufrh not necessarily, formed witheoncentricdye pressions or grooves 7 and 8.

The derdhle lining or filler comprises an elongated tubular hodjy' ofrubber, impervi ous i'ahric, composition, or other flexible yieldingmaterial, either reinforced or without reinforcement, according to ihenature ol2 the inaierial and the conditions of use. ThisY tubular hodj/is of tapered or conical forni, the walls of which also taper or gradu-{all}Y vary in thickness, being of least thick1 ness and mostiiexihle atthe lower or smaller ad oi the hotly and heavier and more refus-haai atthe upper or larger endY thereof. This variation ci thickness of theWalls is leest shown in Fig. 1. lt will he obvious, honorer, that inlieu o varying the thick of the AWalls to correspondingly vary iheelasticity or flexibility of the member,

the Talle may he equal thickness throughout and of varying compositionol" material or it may he reinforced to differentI degrees ihrinigrhozuAiis length, as indicated at 10 in 5, Whereo)Y diilereut degrees ofilexihilitj,v at different points thrmighoutY the th of the liller mayoe insured.

`/ th ition is one S. rifhel mesme stretched and at the saine time willhe devoid orslaclr or looseness. In assembling the device the smallerend of the filler is introduced Within the' housing 1 and is passedthrough the cent al oriice in the ianged opening of the head el. Theinsertion of 'the flange 12 through the opening is' facilitated by theuse of a special instrument inserted through said opening or by meanslof a string which may be engaged about the illerlimniediately above theflange by which the fiance-12 may be drawn through the opening afterwhich the string is disen gaged. ln the adjusted posit-ion of the filler9 the a'nges 11 and 12 engage upon the housing flanges 2 and 5. Theupper end of the lining or filler is secured in position by a cap 13screw threaded upon the housing flange 2 and having a central orifice 1lfor the reception of the teat. This cap 13 hears upon the externalflange 11 of the lining or filler and presses it. Within the annulargroove or channel 7. vit its lower end the filler is held in engagementWith the housing hy means of a nipple plug 15 screwthreaded into theorifice of thehead 4 and hearing" upon the internal flange 12 of thefiller which is thereby compressed intq engagement with the annulargroove or chan-` nel S of the flange 5. The nipple 15 is pro- 95 videdwith a passage orV conduit 1G which communicates with the interiorofthe-tiller 9 or suction chamber. ln practice, this nipple 15 isconnected by a'ilexible conduit with he pail or milk receiver which fisin-turn 100 connected With vthe suction device or vacuum pump. TWhilethe filler or lining may he of smooth interior or exterior or both anddevoid of ribs or longitudinal reinforcing means, as hereinafterdescribed, it is prefcr- Y ahlyv provided with both internal andexterna-l tapered ribs or beads 17 and 1S. These ribs or heads arelargest at the lower or discharge end lof the filler and gradually taperupward. Anf. number of these ribs or reiniiorccment heads may beprovided. ln the drawinghut ve'hare heen shown. The purpose of thereinforcement ribs or beads is to insure the contraction of the liningor iiller uniformly throughoutits periphery. `lil/Hlth Jthe use of aplain lining or filler, it is found in practice that the fillercontracts or collapses from three sides only iu a triangular formation.By the use of a pluralityY of longitudin'allj,7 disposed heads or rein-120 forcement rnc-nhere, such as the ribs 17 and 18, the filler iscaused to collapsemore uniformly throughout the entire circumferenceinasmuch as the filler is made up of a plurality of alternate resistantand' Weak gores. 125 These gores are tapered and oppositely disposed.The Weak gorcs or those intermediate the heads tend to yieldinvvardl,vWhile ythe ribs maintain the general conical shape of the. structure.130

These longiiuliualli' disposed ribs or re intoreing members perform thefurther :t'unetion ot' prerenliingr the braiding.,r or wrinkling ot theliningvorliller transversely, vwhich might tend to rub or eonstriet theteat, causing a congestion ot the blood therein and l'urther tending locause breakage ot the liller walls. Vpon the exhaustion ot' the air tromthe ehainber lf) through the conduit (i the loireitudinallv disposedribs perform the l'urlher t'unctiou ol insuring; the return or expansionot the flexible lower end ot ythe filler to normal position. The.eoustruetion is sueh that the walls intermediate the ribs beineicomparalivel)y thin readily vield to the rariation ot' the internal andexternal pressures, but in so )fielding the), place the lou- ;ritudinalreinforcement ribsl under such tensionV that said ribs will tend toreturn the flexible or eollapsed wallsv upon the equaliz- :ingof thepressure. lt is to be understood that either the inner ribs li or outerribs: le?, or both seriesl ot' ribs, may be. dispensed with it sodesired. lt will be obvious that in lieu ol' the exposed ribs or beadsli and .lil the walls4 ol' the liller ina)v be provided withreiu'loreemeul means longitudinallv disposed therein and embedded orembodied in the wall'sv structure, as shown al 2li in liie'. o.

ll' is obviousl that by reversing the consli'uetion \\'hereb.\' thewalls are at least resistant at the top anillniost resistant at thebottom whereiny they will initiallveollapseai the top.y the eompressiontraveling progre sively downward, an imitation o'l' hand milliing' maybe ell'ected. llnder such eorr.-:trueA tion the eompression ol theliller would elfjlieel the discharge ol milli.

`["roni lhe above (inscription ily will be apparent that there is lliuslprovided a device ot the character desrribed. possessing the, partieularVfeatures ot advaataem liel'ore enumerated as desirable but whirhobviously is susceptible ol' modiliealion in in4 torni, proportion`detail coustrurlion or arrangenient ot parts. without departing tronithe principle involved or sacrificing' anir of its advantages.

lVhile in order lo eoniply with the statute, the invention has beendeserilied i language more or less specilie as to certain sirurrfturalfeatures, it is to be understood that the invention is not limited toany specilie detalla, but that the means and eonstruetion hereindescribed comprises but one inode et Aputting the invent-ion intoeiieet, and` the invention is therefore elaiined broadly in any oil itspossible toi-nis of modifications within the seope ol the appendedelainis.
